So far I am very impressed with it on bottle caps and flat iron junk , all detectors I have owned have been troublesome with these. The one test I messed around with today on both of those I tried the trick ( I think maybe TNSS might have originally posted on) was switching quickly to 5 or 10 khz and seeing the numbers go up , it really works great i dug stuff that went up just to test and everytime the vdi started jumping up it was trash, and when it stayed mostly stable it was a nickel , I think this will work great with gold too. I havent yet been in the areas with square nails with it, but I have been haveing the round nails jump into the higher vdi so much that i have dug quite a few thinking they might be good so this is something I am going to have to learn with this machine. every time I did dig one though my after thought was yeah that just didnt sound quite right but good enough to dig . Oh and this was mostly using field 2 basic set up , the iron bias does seem to help a little.
